Poly(methyl methacrylate) copolymers containing pendant carbazole and oxadiazole moieties for applications in single‐layer organic light emitting devices

Abstract

Methyl methacrylate derived monomers functionalized with pendant carbazole and oxadiazole moieties were synthesized and could be copolymerized to form a random copolymer. The glass transition temperature of the copolymers could be predicted with a Fox equation and ranged from 140 to 191 °C. The photoluminescent characteristics of the copolymers, both in solution and in solid films, exhibited emission that was a combination of sharp and broad peaks, suggestive of monomeric and chromophore aggregation emission. These trends were also apparent in the electroluminescent response of the copolymers, where the appearance of an electromer emission was evident and was tentatively assigned to the carbazole moieties. © 2008 Wiley Periodicals, Inc.

Side-chain conjugated polymers for use in the active layers of hybrid semiconducting polymer/quantum dot light emitting diodes

“…Side-chain conjugated polymers are promising candidates to fulfill the above mentioned criteria and have been previously successfully investigated as host materials in organic LEDs. [30][31][32][33][34] Herein, we report the synthesis of three side chain conjugated polymers which are intended for use in the active layers of hybrid polymer/QD LEDs. The three polymers are com-prised of a polystyrene backbone, carbazole-based electroactive side chains and a disulfide end group.…”

Rational design of methacrylate monomers containing oxadiazole moieties for single‐layer organic light emitting devices

“…The details of the MAK and MAO synthesis are presented in Ref. . In the field of organic electroluminescence devices, the 1,3,4‐oxadiazole fragment possess an exceptional importance.…”

“…; (2)] via the reaction of tetrazoles with aromatic acid chlorides. Figure presents a schematic of the route employed to synthesize the oxadiazole bearing monomers mPND, mNPD, and mNND, while MAK and MAO have been described previously . Finally, to obtain polymerizable oxadiazole structures, methoxy groups were cleaved with concentrated hydroiodic acid and subsequently acylated with methacryloyl chloride to yield final monomers [Fig.…”

Neutral state colorless electrochromic polymer networks: Spacer effect on electrochromic performance

“…M.p. 2-(9H-Carbazol-9-yl)ethyl acrylate (CEA) was synthesized by slight modifications of the corresponding literature procedure on the methacrylate derivative [43]. 1.2 g of HEC (5.7 mmol) was dissolved in 30 mL of DCM in a round bottom flask (100 mL).…”
